4 Claims.

This invention relates to envelopes and has for an object to provide improvements in envelopes which will facilitate the loading thereof V and which will increase the security with which 5 the enclosure is retained in the envelope.

A further object of the invention is to construct the back of the envelope in such a, manner that the upper left hand corner of the face of the envelope where the return address is cus tomarily printed will be completely and evenly supported for printing. 7

Other objects and advantages will hereinafter appear.

In the drawing forming part of this specification,

Figure 1 is a view in rear elevation of an envelope embodying features of the invention; and

Figure 2 is a view of the lining side of an envelope blank adapted to be formed into an envelope like that shown in Figure 1.

The envelope blank comprises a body portion 1 having end flaps 2 and 3, a bottom flap 4, and a sealing flap 5, all integral with it. The body portion 1 is divided from the respective flaps 2, 3, 4 and 5 by fold lines 6, 7, 8 and 9. The end flaps 2 and 3 are folded inward against the body portion 1 and the bottom flap is folded upward and adhesively secured to end flap 2 by a strip of adhesive 10 which runs substantially from end to end of a margin of the side flap 2 overlapped by the bottom flap. The bottom flap 4 is desirably adhesively secured to the end flap 3 by means of a spot of adhesive 11 which may be pulled loose to permit withdrawal of the end flap 3 for postal inspection. The employment of the adhesive spot 11 is optional, however. The closure flap 5 is provided with an adhesive strip 12 which extends along the upper border of the flap far enough to permit adhesive union of the L0 flap 5 with the flaps 2 and 4 but to cause flap 3 to escape contact with the adhesive.

It is a feature of the invention that the upper edge of end flap 2 is cut away abruptly adjacent one end of the envelope as shown at 13. The upper edge of the flap 2 is thus caused to lie a substantial distance below the fold line even at the end of the envelope so that the complete insertion of an enclosure within the envelope and past the fold line 9 is facilitated.

It is a further feature of the invention that the end flap 3 is provided with a tongue 14 near the upper extremity thereof which is adapted to extend for a substantial distance inward beneath the upper end of the back flap. The spot of ad- -55 hesive 11, if used, is desirably applied to this tongue 14. The tongue 14 affords convenient means for securing a spot connection of the end flap 3 to the back flap 4. It further acts as a protection against accidental misplacement of the end flap 3 after the envelope has been opened 160 for postal inspection and the end flap has been tucked back under the end flap and the closure flap 5.

It is a further feature of the invention that the upper edge 15 of the end flap 3 extends in 85 substantial coincidence with the fold line 9. This feature of construction has a two-fold advantage. It provides for the complete and even support of the adjacent corner of the body portion of the envelope in the area where the re- 10 turn address 16 is customarily printed. It also increases the security with which the end flap 3 is held in place after the adhesive spot has been broken.

In accordance with a further feature of the 75 invention, the end flap 3 is provided near the lower extremity thereof with a tongue 17 which extends downward substantially to the bottom of the envelope and increases the security with which the end flap 3 is held in place after the gum 0 spot has been broken. The high upper edge 15, the tongue 14 and the tongue 17 all cooperate to guard the end flap 3 very securely against accidental dislodgment.

I have described what I believe to be the best 5 embodiment of my invention. I do not wish, however, to be confined to the embodiment shown, but what I desire to cover by Letters Patent is set forth in the appended claims.

I claim:

1. In an envelope, a body portion forming a front, a bottom flap and end flaps forming a back, and a closure flap divided from the body portion by a fold line, the upper edge of one of said end flaps being provided immediately adjacent to the end of the envelope with a recessed portion extending to a substantial distance below the fold line of the closure flap to facilitate the thrusting of an enclosure completely into the envelope.

2. In an envelope, a body portion forming a front, and a bottom flap and end flaps forming a back, one of the end flaps being sealed to the back flap along a border thereof and the other being relatively free and constituting a pull flap 105 for postal inspection, the latter flap having a rounded tongue at the lower extremity thereof which extends inward for a substantial distance beneath the lower extremity of the back flap adjacent one corner thereof and downward sub- 1 10 the bottom flap to assist in preventing accidental loss of an enclosure from the envelope both tongues being round and the lower tongue being extended inward and downward substantially to the bottom of the envelope.

4. In an envelope, a body portion forming a front, and a bottom flap and end flaps forming a back,'one of the end flaps being sealed to the back flap along a border thereof and the other being relatively free and constituting a pull flap for postal inspection, the latter flap having tongues at the upper and lower extremities thereof which extend inward for substantial distances beneath the bottom flap to assist in preventing accidental loss of an enclosure from the envelope, both tongues being round and the lower tongue being extended inward and downward substantially to the bottom of the envelope, the

upper edge of said first-mentioned end flap being provided immediately adjacent the end of the envelope with a recessed portion extending to a substantial distance below the fold line of the closure flap to facilitate the thrusting of an enclosure completely into the envelope.
